hi. you problem maybe in power supply unit. couple capacitors bad between power supply to inverter board. good luck!

If the picture on your TV flickers, there may be a simple fix. Here are some possible answers and suggested solutions:

1. Your set-top box may need a simple reboot. Unplug the power connection to the set-top box for about 30 seconds. Reconnect the power and turn the set-top box back on.

2. Check all of your cables for a loose connection by tightening each one with your fingers.Flickers can sometimes be caused by bends in rigid cables, too.

3. If your picture flickers to a black or blue screen, you could have a bad set-top box. Contact your cable or satellite service provider about installing a new one.

4. If you still have audio, the flickering could also mean that you have a failing backlight.

For additional troubleshooting information, check out the chart at TV flickering for more solutions. I hope this helps!

If for example a Samsung it is in the power supply of the set--no brand or model number indicated here so that limits the scope of a possible answer.

You have been the victim of a power surge. It will need to be repaired in order to work.

Make sure you have the PS3 set to the correct frequency for the TV. Many cannot accept 1080p / 24fps etc.

Try different settings.

I hope this helps.

Flickering screen display

Flickering on the screen can be caused by defective hardware in the computer or by improperly installed software, but it can also be caused by interference from external devices. The following examples describe situations in which your screen could start flickering:

• Screen starts flickering because of interference caused by devices which generate magnetic fields, for instance:
  • a TV set
  • a laser printer
  • another monitor
  • fluorescent lights
  • hidden power lines
• Apart from interference, an incorrect setting in your system CMOS setup can also cause flickering. On some systems it is possible to distinguish between interlaced and non-interlaced monitors. The setup of your system should always be colour non-interlaced.
• Proximity to the monitor of fans, air-conditioning units or other devices with rotating motors.
• The number of devices using power from the same electrical line. Are you overloading the plug?
• Monitor placed on an unstable surface.
• Improper video drivers, this is a software problem, see section B
• An improperly configured or a defective video card.
